We recommend that you update the license server to the latest version, but in some situations you will need to do this. This article describes how to perform this upgrade on Windows systems. It assumes you have already have an older version up and running and that it was installed as a service using the 'installs' utility that we supply.
"I have used pretty much all of the simulators out there, Hspice, HPspice, PSpice, Mspice, Accusim, Spectre, SpectreRF and the list goes on... but none are as simple, straightforward to use as SIMetrix."
We recommend that you update your license server using the GUI installer flex_install. This program will detect your existing license server and remove it before installing the updated license server. The procedure for updating is the same as for installing afresh.
